Oxygen sensor circuit
Description
In order to obtain a high purification rate of the carbon monoxide (co),
hydrocarbon (hc) and nitrogen
oxide (nox) components in the exhaust gas, a twc is used. For the most efficient
use of the twc, the
air-fuel ratio must be precisely controlled so that it is always close to ...
